Keeley McKee was three years old when her mother, Leanne McKee, was killed by her partner in March 2003, weeks before the couple were due to marry. Her mother's partner then took his own life. Ms McKee, who was staying with her grandmother that night, was kept from the full circumstances of her mother's death as she grew up.
She told the BBC's Good Morning Ulster programme that as a young child her mother would tell her to hide in a bedroom and not come out until called, and that she believes the partner her mother was frightened of had tried to get in.
At 18, Ms McKee found a news report online about her mother's death. "I had an idea but I think I was in denial. I didn't want to believe it and I didn't want to face it," she said. "I read it in the most brutal way you could probably read something like that. I think from that time then, I just ran away from grieving."
She described feeling angry and confused, withdrawing from friends and family, experiencing suicidal thoughts and attempting to take her own life on multiple occasions. She also struggled with drug and alcohol misuse, and said the consequences of her mother's murder shaped how she viewed love and relationships. "I was scared to fully love in case that was taken from me again," she added.
Ms McKee credits a Christian discipleship programme with helping her confront the past. "It gave me the fuel, it gave me the fight to say: 'I'm not being a victim of this anymore. My mum was a victim. I'm not being a victim of this story. I am going to do something about it'," she said.
She said she believes violence has become normalised in society and wants greater recognition of the lasting impact domestic abuse has on the children and families left behind. She hopes her story will encourage people experiencing abuse to seek help and consider the example they set their children. "It's just going to go from generation to generation," she said.
Ms McKee was brought up by her great-aunt and great-uncle, who took her into their home while grieving for Leanne themselves. She said their support helped her through some of the most difficult periods of her life.
